Patent EP-0210631-A2 (EP)
Inventor: NIIJIMA HIRONOBU
IPC: H01L21/027
Filed: 1986-07-28
Abstract: The present invention is directed to a method and apparatus for drawing, by an electron beam, patterns on a semiconductor wafer for the fabrication of an integrated circuit. Chip areas on the semiconductor wafer are each divided into rectangular blocks arrayed in rows and columns. The deflection field (204) of the electron beam is selected slightly larger than each block. Real block marks (22aO, 22a1, ... 22b0 and 22b8) for indicating the positions of respective blocks (abl, ab2,...) are provided on every side of the chip area. The specimen is fed so that a block array (abl, ab2, ...) starting at one comer of the cip area passes through the deflection field along one side of the array. Upon detection of the block marks at three corners (22aO, 22a1, 22b0) of a first block (abl) of the array, correction coefficients for the block are computed based on the positions of the three detected real block marks and then an imaginary block mark (23b1) is set at the remaining corner of the block (abl) on the basis of the correction coefficients. Thereafter, upon each detection of one real block mark (22a2, 22a3, ...) for each block (ab2, ab3, ....) of the block array, correction coefficients are computed based on the position of the newly detected real block mark (22a2), the position of the real block mark (22a1) detected for the immediately preceding block (abl), and the position of the imaginary block mark (23b1) set for the immediately preceding block (ab1). and an imaginary block mark is set for for the block (ab2) on the basis of the correction coefficients. Pattern data for each block is corrected according to the correction coefficients thus obtained and a pattern is drawn in the block in accordance with the corrected pattern data.

Abstract: Light guides (5, 6) which in specific regions (9) are coupled with regard to signals are provided on a support (1). The degree of coupling is varied in the event of pressure on a cover foil (2) above the regions (9). This leads to a change in the light signal at the keyboard output. The keyboard enables simple and interference-free switching of light signals with a small outlay. <IMAGE>

Abstract: 57 A pump has a reciprocatable pumping member driven by the actuator 14 shown, which comprises a cylinder 24 closed by a plunger 26. A hollow partition 28 divides the space between the plunger 26 and the cylinder 24 into two drive chambers 30a, 30b. Fluid can be selectably supplied at constant pressure to one or to both of the chambers to act on one or both of the faces 38, 40 and drive the plunger along the cylinder with differing force. The volume of fluid required to fully extend the actuator also differs, so that the actuator may be driven quickly or slowly with a low or high driving force from a supply providing fluid at a constant rate and pressure.

Abstract: @ Light generated by one ormore chemical reactions in a discrete array is determined, both as to emissions per reaction and as to relative location of the reactions, e.g. using a system comprising:
     a sample carrier having spaced-apart discrete areas each containing a reactant capable of emitting light photons if a reaction takes place;   a photon receiver, for receiving photons emitted from each reaction simultaneously; and   a signal generator coupled to the photon receiver, for generating a signal representing the x-y location of each reaction.   
     The signal generator may be a photomultiplier, charge-coupled device or vidicon tube. The invention is particularly suited to the determination of reactions and non-reactions, e.g. between an array of labelled antibodies and a specimen potentially containing one or more complementary antigens, in an immunoassay.

Abstract: In a TDMA system comprising a plurality of earth stations communicable with one another by the use of a plurality of carrier waves through a transponder of a satellite which has an available electric power level, bursts carried by the carrier waves are individually and flexibly controlled in accordance with a burst time plan so that selected ones of the carrier waves have on the satellite a total electric power level which does not exceed the available electric power level at any time. The bursts therefore may have different power levels in dependency upon scales of the earth stations, traffics carried by the bursts, and receiving conditions at the earth conditions. The selected carrier waves can be transmitted or received by frequency hopping. Such control of the power levels is carried out in each earth station by the use of a combination of an attenuator (67) and an attenuation control circuit (71) operated in accordance with the burst time plan.

Abstract: A flying platform (10), propelled by at least one ducted fan (11) causing a vertically downwardly directed airstream in and through a cylindrical duct (12). A vane system in the duct (12) has two mutually perpendicular pairs (31-34) of diametrically opposite first vanes, each extending in from the duct rim toward the center of the duct. Each pair of first vanes provides a pair of generally vertical walls parallel to a diametral line across the duct, and they define duct passages between the pairs of vanes and define quadrants between adjacent pairs. Each first vane has an upper, fixed, rigid portion and a variable camber flap (45, 46) depending therefrom. A first servomotor with linkages vary the camber of each pair of flaps (45, 46), so that the camber of the flaps (45, 46) of each pair is at all times the same amount but in opposite directions. Preferably, there are also four second vanes (41-44), one bisecting each quadrant, and a symmetric pair of spoilers (75-82) is mounted on each second vane (41-44). Each pair of spoilers (75-82) is independently movable, as a pair continuously between a position substantially blocking airflow through the outer portion of said quadrant and a position permitting substantially full airflow therethrough. A second servomotor with linkages symmetrically varies the position of its spoilers (75-82). There may be a radio receiver responsive to remote control signals for actuating each servo­motor and its linkages.

Abstract: A tool face orientation of a directional drill bit within a borehole is efficiently communicated to the well surface by communicating only changes in the tool face orientation. In the first embodiment after the entire tool face orientation is measured and transmitted uphole, and thereafter changes of the tool face orientation as measured with respect to the center of spatially fixed sectorial ranges are transmitted uphole. The magnitude of the changes relative to the center of a fixed sectorial range, being smaller than the range of the entire tool face orientation, allow the subsequent transmission to be made using words of shorter length. Alternatively, the changes in tool face orientation may be measured with respect to a sliding reference point. The sliding reference point may, for example, be the mean value of the prior ten measurements and any previous mean values. The sliding sector will then be held until change in the tool face orientation cause the tool to go out of the sectorial range of the sliding   reference point, at which point a new sliding reference is defined which inherently includes the tool face within its range.

Abstract: An apparatus for use in testing an integrated circuit in its intended operating environment with­in a hybrid circuit includes a hybrid circuit of the type within which the integrated circuit is to operate when subsequently mounted thereon. An aperture is formed in a hybrid substrate of the hybrid circuit in a location where the integrated circuit would otherwise be mounted, and a dielec­tric membrane is clamped over the aperture. Con­ductive bumps in the underside of the periphery of the membrane engage conductors on the upper surface of the hybrid substrate surrounding the aperture which conductors would normally connect to termi­nals of the integrated circuit. Conductive bumps on the under side of a central area of the membrane engage contact areas on the contact face of an integrated circuit under test situated therebelow and a plurality of conductor runs supported by the membrane extend from the conductive bumps in the central area of the membrane to the conductive bumps in the periphery of the membrane, thereby electrically interconnecting the integrated circuit under test to the hybrid circuit.
